Will the Milky Way and Andromeda galaxies collide in several billion years? The odds have changed with a new study using ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star ...

Simulating a billion years using previous best-resolution simulations would take almost 36 years of real computing time. When you purchase through links on our site, we may earn an affiliate ...

Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and Small Magellanic Clouds. The evidence is a stream of gas called the ...

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, ...

Head-on (left) and side-view (right) snapshots of a galactic disk of gas. These snapshots of gas distribution after a supernova explosion were generated by the deep learning surrogate model.

We cannot see or image the entire Milky Way galaxy, because we are located inside it. From Earth, we can observe only a portion of the galaxy, and when we look up at the dark, clear night sky from a ...

The original Mass Effect trilogy is pretty cool. But know what’s really cool? Mass Effect: Andromeda. Tomatoes down, please! Of course, grass that’s 2.537 million light years away isn’t always greener ...

So it’s confession time: I’ve been lying to you. I’ve said on many occasions that our Milky Way galaxy has a flat disk (like in this column or this one). But it’s not really flat—not even for a ...

The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars. But that’s just the visible light. Observing the sky in ...
